Winds and wind systems on the Earth. 1  Wind is formed by the flow of air in horizontal directions. In meteorological definitions the coming direction of the wind is called wind direction. 2  1 m/s = 3.60 km/hr = 2.24 mph = 1.94 knot.
The production of proteins involves two major steps: transcription and translation. Together, transcription and translation are known as gene expression. The process of transcription only involves two molecules: DNA and RNA. A DNA strand provides a template for the synthesis of a complementary RNA strand. This process is used to synthesize any type of RNA from a DNA template. Transcription of a gene produces a messenger RNA (mRNA) molecule.
Translation is the process of making peptide strands from primary transcript. There are a set of aminoacids which are carried to the site of translation by specific transfer RNAs for the process. Apart from this messenger RNAs and ribosomal RNAs also play significant roles in translation. Comparison: Transcription vs. Translation in DNA Precursor molecule â For transcription the DNA is the parental strand where as for translation it is the primary transcript (RNA). Functionâ Transcription produces an RNA molecule complementary to the DNA strand where as translation produces the peptide sequence which is complementary to the RNA (same as the DNA sequence).
